The results showed that the essential oils tested varied in their antimicrobial activity. Generally they have antibacterial effects at low concentrations (from 0.1 to 0.001%) except thyme and oregano. Essential oils of basil and savory have antifungal effect at 0.01% concentration while thyme, oregano and funnel at 0.1 and dill at 5.0% showed antifungal effect. Individual plant essential oils can inactivate pathogenic and spoilage microorganisms in foods, efficiently aid rancidity in foods, and adequate shelf -life of foods. © 2003 Taylor & Francis Group, LLC.en10.1080/0972-060X.2003.10643340info:eu-repo/semantics/openAccessArticle62130134N/A
